It doesn't have to be all gamer RGB, but, for me, it has to look well-designed, e.g., like Apple products. The Steam Machine looks fine, but the controller looks cheap and all the buttons seem too far away from each other, as if it's meant to be held by someone with large hands.

Oh, I was just talking about the steam machine.

For a controller, I don't care how it looks at all. All that matters is how it feels.

Nothing really looks like Apple products except Apple products though, so you are locking yourself out of buying pretty much anything except Apple with this idiosyncrasy. Which I'm sure Apple is quite pleased about.
